the success rate of several advanced basic and clinical techniques in the field of mammalian biotechnology, including cloning, pre-implantation genetic diagnosis, and assisted reproductive techniques (art) depends mainly on the success rate of pregnancy following in vitro fertilization-embryo transfer (ivfet). the techniques used in art have advanced considerably since the first in vitro fertil...

introduction: in cases of poor satisfaction with aphakic glasses and intolerant or reluctant to use contact lenses, secondary intraocular lens (iol) implantation provide an alternative aphakic vision correction. this study aimed to evaluate surgical problems.  intraoperative and postoperative complications and visual acuity outcomes of secondary anterior and posterior chamber intraocular lens i...

Nickel films of 300 nm thickness were deposited by electron beam evaporation at room temperature on 316 stainless steels. Corrosion studies of Ni coated 316 SS have been performed after N+ ion implantation at different energies of 20, 40, 60 and 80 keV. The structure and surface morphology of the films were evaluated using X-ray diffraction (XRD), atomic force microscope (AFM) an...

Background: To evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). Materials and Methods: In this randomized placebocontrolled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) were randomly assigned to receive 250 μg i...

background: apoptosis is a process that plays an important role during early stage of implantation. the aim of this study was to investigate the incidence of apoptosis in mice endometrium after ovarian stimulation at implantation period. methods: nmri female mice were divided into two groups: 1) control group, which were rendered pseudopregnant by vaginal stimulation and 2) experimental group, ...

Introduction: Parents are such important members of the cochlear-implant team that analysis of their views is essential in orderto improve services and outcomes. The authors developed a tool to assess parental attitudes towards various aspects of cochlear implantation in children who had passed aural rehabilitation sessions. The authors then went on to determine the validity and reliability of ...

background: the aim of this study was to investigate in vivo biocompatibility of resilon, compared with gutta-percha, at short and long-term following implantation in a rat subcutaneous implantation model. materials and methods: male wistar rats were implanted subcutaneously with either resilon or gutta-percha or were sham controls. tissues were harvested at 8 days or 60 days after implantation...

Objective(s): Progestrone is a prequisite for pre-implantation angiogenesis and induce decidual angiogenesis. It is unknown the effect of progestrone administration on the endometrium of hyperstimulated mice at pre-implantation time. Material and Methods: Adult female NMRI mice were divided in three groups [control group, ovarian stimulated group and progestrone treated mice after ovarian stimu...

Cochlear implantation is a method used for the treatment of patients with profound hearing loss. This procedure may the accompanied by some major or minor complications. We evaluated the surgical complications of cochlear implantation in Fars province (south of Iran). A total of 150 patients with cochlear implantation were enrolled in the present study. Most of the patients were pre-lingual chi...
